The Vishay Dale SM8S43AHE3_A/I is a high-reliability Transient Voltage Suppressor (TVS) diode designed for sensitive electronics protection. It features a surface mount DO-218AB package and is optimized for high temperature stability.
This unidirectional TVS diode offers a working voltage range of 10V to 43V and a breakdown voltage range of 11.1V to 52.8V. It boasts a significant peak pulse power dissipation of 6600W (10 x 1000 μs waveform) and a peak forward surge current of 700A. The device operates across a wide temperature range from -55°C to +175°C.
Key features include junction passivation optimized design, low leakage current, low forward voltage drop, and high surge capability. It meets ISO7637-2 surge specifications and is AEC-Q101 qualified, making it suitable for demanding automotive load dump protection applications. The molding compound meets UL 94 V-0 flammability rating, and terminals are matte tin plated for solderability.
Applications include protection against voltage transients induced by inductive load switching and lighting, particularly in automotive environments. Its high temperature capability and reliability make it a robust choice for critical systems.
